COTTON-CLEANER.

Specification of Letters Patent No.v31,069, dated January 1, 1861.

To all whom it may concern:

Be it known that the following, taken in connection with the accompanying drawing, which forms part of this specification, is such a full and clear description of the Improvement in Machinery for Cleaning Cotton, or Cotton-IVhippers, invented by COLIN S. TARPLEY, late of Jackson, in the county of Hinds and State of Mississippi, deceased, as that others will be enabled therefrom to make and use the same.

Referringto the accompanying drawing, Figure l represents a vertical longitudinal section of a cotton cleaner orwhipper constructed according to the present improvement; Fig. 2 a transverse vertical section thereof; Fig. 3 an end elevation, and Fig. 4 a horizontal section of the same.

In this machine, which is for extracting dust and vdirt from the cotton, the part marked A in the accompanying drawing represents a hopper to receive the seed cotton requiring to be cleansed.

B is the whipper chamber into which the cotton passes from the hopper, and C, C are two whippers revolving therein and situated so as to receive the cotton between them. These whippers are formed of shafts or drums armed with teeth (c 0) arranged in four-more or lessrows along each shaft, at a suitable distance apart in the several rows from each other, and sothat the teeth of the one whipper interlock or pass between the teeth o'f the adjoining whipper. Both whippers (C, C) revolve in like directions simultaneously whereby their teeth interlock or pass between each other in opposite directions. This action of the whippers serves to detach much of the dust dirt and trash and to divide the cotton into small locks, while breakage of parts by any coarse obstruction and injury to the liber is avoided by the one whipper (C) driving the other (C) through a belt l (b) acted upon and kept at a driving tension by a roller clamp or pressure bar (D) hung so as to be capable of yielding and held down to bear on the belt by a spring d. Such provision insures the uniform action of the whippers under all proper or ordinary resistance but admits of slip or back action of the one whipper in case of extraordinary or improper resistance. Any

4and from beneath which ioor said dust dirt and trash is passed off by an inclined floor (G) to a boX or other receptacle that may be emptied from time to time as needed.

H, is afan set in motion by a belt (e) from the one whipper (C).

opening or flue (I) to act upon the cotton in its descent from the whipper chamber exit (E) to (say) the gin mouth, to effect more perfect clearance of dust or trash adhering to the cotton and which the whippers may'have only served to loosen without detaching but which a fan blast, thus acting upon the cotton in its free descent and after being acted upon by the whippers, effectually secures the separation of. What is he're claimed, as new and useful, 1s: ,f

The combination of the sieve Hoor (F), whipper chamber (B) having feed and delivery apertures substantially as described, whippers or beaters (C C), and blast flue (I), when the latter or blast chamber is separated from the dust chamber by the close partition (G), essentially as shown and described.

In testimony whereof, we have hereunto subscribed our names.
